About Converting Metric tons per Cubic foot to Imperial hundredweights per Cubic Millimeter
Metric ton per Cubic foot and Imperial hundredweight per Cubic Millimeter both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Both are mass per volume density units.
Formula
imperial hundredweights per cubic millimeter = metric tons per cubic foot × 6.951385e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 metric ton per cubic foot equals 35314.6667215 base units, and 1 imperial hundredweight per cubic millimeter equals 50802345440 base units, so dividing one by the other gives the direct metric ton per cubic foot-to-imperial hundredweight per cubic millimeter factor of 6.951385e-7.
Simple example
1 t/ft3 × 6.951385e-7 = 6.951385e-7 long cwt/mm3
1 metric ton per cubic foot = 6.951385e-7 imperial hundredweights per cubic millimeter.
Real-world example
1,000 t/ft3 × 6.951385e-7 = 0.0006951385 long cwt/mm3
1,000 metric tons per cubic foot = 0.0006951385 imperial hundredweights per cubic millimeter.

What is a metric ton per cubic foot?
Metric ton per Cubic foot (t/ft3) is a unit of density.
What is a imperial hundredweight per cubic millimeter?
Imperial hundredweight per Cubic Millimeter (long cwt/mm3) is a unit of density.
Is the metric ton per cubic foot to imperial hundredweight per cubic millimeter conversion exact?
Yes. Both metric ton per cubic foot and imperial hundredweight per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 6.951385e-7 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
